The problem shown here applies to elemental functions in general, not only
(elemental) intrinsics, see below for an example:

$> cat assign.f90
real :: a(3) = 0.0, b(2) = (/ 0.0, 0.1 /)
a = COS(b)
print *, a
end

$> gfortran-svn assign.f90 && ./a.out
   1.000000      0.9950042       1.000000


$> ifort -warn all assign.f90 && ./a.out
fortcom: Error: assign.f90, line 2: The shapes of the array expressions do not
conform.   [A]
a = COS(b)
^
compilation aborted for assign.f90 (code 1)

$> sunf95 -w4 assign.f90 && ./a.out

a = COS(b)
  ^
"assign.f90", Line = 2, Column = 3: ERROR: The left and right hand sides of
this array syntax assignment must be conformable arrays.

f90comp: 4 SOURCE LINES
f90comp: 1 ERRORS, 0 WARNINGS, 0 OTHER MESSAGES, 0 ANSI

Same example as above with elemental function:

$> cat assign.f90
real :: a(3) = 0.0, b(2) = (/ 0.0, 0.1 /)
a = f(b)
print *, a

contains
  real elemental function f(x)
    real, INTENT(iN) :: x
    f = cos(x)
  end function
end

$> gfortran-svn assign.f90 && ./a.out
   1.000000      0.9950042       1.000000
